[csa] Tnodify builtins-async-generator-gen.cc
Remove TaggedIsAsyncGenerator since all but one use is to generate asserts that are handled automatically by TNodes. The remaining use is then just inlined. Also removes unused IsFastJSIterResult function. Bug: v8:6949 Change-Id: Id5631586b7e4d4f43d352493a3e2638cf449665f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1849516 Commit-Queue: Dan Elphick <delphick@chromium.org> Reviewed-by: Santiago Aboy Solanes <solanes@chromium.org> Cr-Commit-Position: refs/heads/master@{#64186}
